038 103 085C – Camshaft / Crankshaft Seal (Priced Each)

Description

The 038103085C Seal is a high-performance sealing component designed to prevent engine oil from escaping the cylinder head or block at the camshaft and crankshaft exit points. This 038103085C Seal features the updated PTFE (Polytetrafluoroethylene) lip design, which represents a significant technological advancement over traditional rubber seals. Consequently, this modern design provides superior thermal stability and reduced friction during high-speed engine operation.

Proper sealing at these rotating shafts is critical for maintaining internal oil pressure and protecting the engine bay from contamination. Furthermore, this seal is engineered to withstand the constant heat and pressure associated with the engine’s timing system. Therefore, choosing a high-quality 038103085C Seal helps keep your engine clean and ensures your timing belt remains free from damaging oil soak.

Why the 038103085C Seal Matters

The camshaft and crankshaft are the primary rotating assemblies responsible for engine timing and power delivery. If the 038103085C Seal fails, however, pressurized oil can leak directly onto the timing belt or serpentine belt. Consequently, the rubber belt material can degrade rapidly, leading to premature belt failure or catastrophic timing jumps.

Unlike older seal generations, this PTFE version does not utilize a metal tensioning spring. Instead, it relies on the “memory” of the specialized material to form a tight bond with the metal shaft. Furthermore, this prevents the common “grooving” of the camshaft or crankshaft that often occurs with spring-loaded seals. Moreover, installing this updated unit ensures your lubrication system meets modern factory standards for leak prevention.

Signs of Failure

Inspect your vehicle for these symptoms of a failing camshaft or crankshaft seal:

• Oil pooling on the ground directly beneath the front of the engine block.

• Visible oil residue or “wetness” around the timing cover or crankshaft pulley.

• Squealing belts caused by oil contamination on the pulley surfaces.

• Burning oil smells as leaking lubricant reaches hot engine components.

• Significant oil buildup on the lower engine tray or underbody panels.

• Premature wear or swelling of the timing belt during inspection.

Key Features — 038103085C Seal

• OE Part Number: 038 103 085 C

• Seal Design: Modern PTFE sealing lip without an internal garter spring.

• Function: Provides a leak-free seal for the camshaft or front crankshaft.

• Durability: High resistance to chemical degradation and extreme temperatures.

• Precision: Dimensions of 32x47x10mm for exact factory fitment.

• Value: Critical maintenance item priced individually for flexible repair needs.

Service Notes

Always verify fitment by VIN before ordering. PTFE seals require a very specific installation procedure to function correctly. Failure to follow these steps will result in immediate and permanent leaks. Furthermore, the mating surfaces on the shaft must be perfectly smooth and free of burrs.

Compatibility

Always verify fitment by VIN before ordering. This 32x47x10mm seal is widely used across Volkswagen, Audi, and Porsche applications.
